Stop in for a cup of coffee

Tell you what I was off the grid when I lived in Hawaii. I do not miss doing the monthly maintenance on all those trojan 105's we had in series parallel to run the inverter. Clean all the terminals then top them off. all under the house that was two feet off the ground.
Government job. Had a genset,and 2 24 volt battery banks. Ran an inverter for nighttime use.
Was hard on batteries.
In all their wisdom they decided adding 4 more batteries would fix the battery reserve issues.
Flat out refused to replace the weak ones. Until one shorted.
Killed the whole works.
The biggest problem with something like that is mis-matching batteries. They wouldnt listen. I warned them.
